The edge of halide perovskites: surfaces and interfaces drive solar efficiency and stability

Chem. Soc. Rev., 2026, Advance Article DOI: 10.1039/D5CS00636H, Tutorial Review Diana K. LaFollette, Kunal Datta, Juan Tirado, Michel De Keersmaecker, Erin L. Ratcliff, Juan-Pablo Correa-Baena Halide perovskites are promising for next-generation optoelectronic applications, but further efficiency gains are limited by interfaces. This review discusses key interfacial roles, materials design strategies, and advances in characterization.
